Hi @yeongchan1228 thank you for reporting! I have confirmed this iOS-specific error message does happen even when you intend to run on Android. To my knowledge there isn't a way to specify you only want a single platform's config changes to be applied, the plugin will always apply to both iOS and Android.

On the iOS side we require ios.bundleIdentifier to be specified as we use it to modify the config to include the Notification Service Extension.

In your app.json file you will need to specify the bundle identifier:

    "ios": {
      "supportsTablet": true,
      "buildNumber": "<your_build_number_here>",
      "bundleIdentifier": "<your_bundle_identifier_here>"
    },

If you don't intend to ever deploy to iOS, you can provide any non-empty string to the bundleIdentifier, the Android builds will work!

I've noted our README does not include this information. I will leave this issue opened until we can get the README updated to indicate ios.bundleIdentifier is also required to exist. Thanks!
